The paper proposes a cross-layer approach for joint closed-loop control of wireless video transmission to multiple users. The approach allows joint adaptation of the multiple users source rates by maximizing the worst served user video quality, taking into account the characteristics of the video sources, channel conditions and user requirements. The controlling task is split in two parts: resource allocation between users and cross-layer optimization for each user. A novel simple algorithm for dynamic resource allocation between users is proposed in conjunction with single user rate control.

Abstract

The paper proposes a cross-layer approach for joint closed-loop control of wireless video transmission to multiple users. The approach allows joint adaptation of the multiple users source rates by maximizing the worst served user video quality, taking into account the characteristics of the video sources, channel conditions and user requirements. The controlling task is split in two parts: resource allocation between users and cross-layer optimization for each user. A novel simple algorithm for dynamic resource allocation between users is proposed in conjunction with single user rate control.
